Application filed March 11, 1951. Serial no.f21,e 7s.

This invention relates to a plot and lot marker. The object of the invention is to provide a marker hich may be used to permanently and accurately mark the corners of lots, cemetery plots, etc.; and, further, 5 to provide a marker which offers relatively great resistance to its removal from the to Fig. I; Fig. III is an elevation of a ma, ified form of marker; Fig. IV is an isometric fragmentary view of the lower portion of the marker shown in Figures I and II; and Fig. V is a plan'view of the marker '20 shown in Figures I, II and IV.

My marker is cast of a suitable metal such as a non-corrosive bronze, and comprises primaril the shan and a head 3 disposed at the end of the shank opposite the vane, and arranged to extend at right angles to the longitudinal axis of the shank. Shank 1 comprises two intersecting legs or webs la or 1b,

and terminates in the vane 2 which is of rectangular contour in elevation, and which has portions 2a of relatively great area formed as continuations of the web 10!. of the shank. 1

The head 3 of the marker is a plate shown as circular which lies upon the surface of r the ground or other material into which the marker is driven. As shown, the marker head is provided with one or morerelatively deep score lines 3a to indicate the exact line of division between plots. The head may be provided with a punch mark or other index, to serve, as a bench mark for land recording, surveying, and the like. 5 Immediately beneath the head, the shank webs 1a are extended to provide additional supporting webs 4 for the marker head.

, In the use of the marker, it is desirably first supported by a suitable 'anvil or the like, and appropriate markings made on the a shank 1, a terminal vane 2 on I upper surface of head 3, bymeansof an indentingjdie ,or' dies. During this marking, probability of-breaking the relatively flat headBis minimized by the's'upporting webs l w hic h underlie the head. f;

driving the marker; terminal vane T2 at the lower endiof shank -1 serves as a blade to enter the ground andfacilitate driving the marker" as ,a; whole} When the marker has been driven "in p osition vits form pre i vents it :from being worked loose in the ground. ,,The lateral. movement necessary for working. the marker loose. is resisted. by the intersecting webs 1aand1b of "the shankpand, is also resisted bythe terminal vane 2.. It is .difiicult to loosen terminal v 2 i he gr nd. a y lig gu r movement ls-fresisted because 30f the rela;

;tively ide spread of its extending portions j As but little leverage can bejobtained f 2a. by working thehead 3, it is necessary that the marker be dug from the ground when it has once been driven in to its full length; The marker as a whole forms a simple integral casting since the extensions 2a of a the vane 2 andthe supporting webs 4 for the head 3 are formed as extensions of the shank web 1a. The. proportions of the marker are such as to obtain a maximum of security when the marker isdriven, without 30 unduly increasing the size of the marker and the quantity of metal comprised in it.

Themodified form of marker shownin' Fig. III of the drawing is identical with the form shown in the other figures, with 5 the exception that. the shank webs 1a and 1b are serrated in such manner that shoulders 5 are formed in staggered position around theshank of the marker. Obviously a the shoulders 5 do not resist driving of the marker, but. do serve to increase the difliculty of withdrawing the marker by means of a straight pull. In this form of marker also the terminal vane 2 and the intersecting webs la and 1b prevent loosening of thegr, marker in the ground by attempts to mov it laterally to provide clearance. i

I claim as myinvention:

1. A plot marker formed as single metallicdriving piece comprising a shank formed of intersecting ground engaging websyaflattened marker head on said shank disposed at right angles to the longitudinal axis of the shank, one of said intersecting Webs extended terminally to form a plane 'ground penetrating and engaging member with a penetrating edge lying at right angles to the longitudinal axis of the shank and extending in opposed directions outwardly from the shank, said member being of sub- I stantial depth throughout its lateral extent to present terminally disposed surfaces of relatively great area resisting turning movement of the marker When driven. i 7

2. A plot marker formed as a single me tallie driving piece comprisin' a shank formed of intersecting groun engaging Webs,-a flattened marker head on said shank disposed at right angles to the longitudinal axis of the shank,"one of said intersecting Websextendedterminally to form' a plane ground penetrating and engaging member with a'penetrating edge lying at right angles to the longitudinal axis .of the shank and extending in opposed directions outivv'ardly from the shank, said member being of substantial depth throughout its lateral extent to resent terminally disposed surfaces of re' atively great area resisting turningmovement of the marker When driven; andst'rengthening Webs beneath the head of the marker formed as lateral extension of at least one Web of the shank. I In testimony whereof 'Ihave hereunto set my hand. R MASON.
